[jira] [Commented] (YARN-3047) set up ATS reader with basic request serving structure and lifecycle

    [ https://issues.apache.org/jira/browse/YARN-3047?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14284130#comment-14284130 ] 

Varun Saxena commented on YARN-3047:
------------------------------------

[~sjlee0], wanted to know whether we will have a single instance of ATS Reader which the clients will connect to for querying. And this instance can in turn launch multiple threads to query storage in parallel.
Or a global instance which distributes requests to multiple instances of ATS readers ?

> Per design in YARN-2938, set up the ATS reader as a service and implement the basic structure as a service. It includes lifecycle management, request serving, and so on.
